    Question

    What should come in place of the question mark (?) in the given series?
    24, 30, 25, 29, 26, ?

    A.

    28

    B.

    32

    C.

    30

    D.

    27

    Correct option is A

    Given: 24, 30, 25, 29, 26, ?
    Logic: Odd positions increasing by + 1 and even positions decreasing by - 1 place.
    Odd positions:
    24, 25, 26 → increasing by + 1
    Even positions:
    30, 29, ? → decreasing by - 1
    Continue the even-position pattern
    30 → 29 → 28
    So, the missing term is 28.
    Thus, correct option is (a).
